Second bikie shot in gang war in Sydney

Warring factions in the Comanchero bikie gang may be responsible for two shootings within three days that have left one of their members dead and the other clinging to life.

Police urged calm on Tuesday, saying the community shouldn't fear "open-gang warfare" in the streets of Sydney.

The call came after a 28-year-old man known to police was shot four times in the stomach about 5am (AEDT) in a car park at Rhodes, in the city's northwest.

The wounded man, who police confirmed was a Comanchero member, left a trail of blood as he stumbled 500 metres past Rhodes train station and a childcare centre, calling for help before collapsing in front of a construction site in Rider Boulevard.
